text: 'We introduce two novel methods for learning parameters of graphical models
for image labelling. The following two tasks underline both methods: (i) perturb
model parameters based on given features and ground truth labelings, so as to
exactly reproduce these labelings as optima of the local polytope relaxation of
the labelling problem; (ii) train a predictor for the perturbed model parameters
so that improved model parameters can be applied to the labelling of novel data.
Our first method implements task (i) by inverse linear programming and task (ii)
using a regressor e.g. a Gaussian process. Our second approach simultaneously
solves tasks (i) and (ii) in a joint manner, while being restricted to linearly
parameterised predictors. Experiments demonstrate the merits of both approaches.'

text: Synchronous programs are easy to specify because the side effects of an operation
are finished by the time the invocation of the operation returns to the caller.
Asynchronous programs, on the other hand, are difficult to specify because there
are side effects due to pending computation scheduled as a result of the invocation
of an operation. They are also difficult to verify because of the large number
of possible interleavings of concurrent asynchronous computation threads. We show
that specifications and correctness proofs for asynchronous programs can be structured
by introducing the fiction, for proof purposes, that intermediate, non-quiescent
states of asynchronous operations can be ignored. Then, the task of specification
becomes relatively simple and the task of verification can be naturally decomposed
into smaller sub-tasks. The sub-tasks iteratively summarize, guided by the structure
of an asynchronous program, the atomic effect of non-atomic operations and the
synchronous effect of asynchronous operations. This structuring of specifications
and proofs corresponds to the introduction of multiple layers of stepwise refinement
for asynchronous programs. We present the first proof rule, called synchronization,
to reduce asynchronous invocations on a lower layer to synchronous invocations
on a higher layer. We implemented our proof method in CIVL and evaluated it on
a collection of benchmark programs.

text: It has been reported that nicotinamide-overload induces oxidative stress associated
with insulin resistance, the key feature of type 2 diabetes mellitus (T2DM). This
study aimed to investigate the effects of B vitamins in T2DM. Glucose tolerance
tests (GTT) were carried out in adult Sprague-Dawley rats treated with or without
cumulative doses of B vitamins. More specifically, insulin tolerance tests (ITT)
were also carried out in adult Sprague-Dawley rats treated with or without cumulative
doses of Vitamin B3. We found that cumulative Vitamin B1 and Vitamin B3 administration
significantly increased the plasma H2O2 levels associated with high insulin levels.
Only Vitamin B3 reduced muscular and hepatic glycogen contents. Cumulative administration
of nicotinic acid, another form of Vitamin B3, also significantly increased plasma
insulin level and H2O2 generation. Moreover, cumulative administration of nicotinic
acid or nicotinamide impaired glucose metabolism. This study suggested that excess
Vitamin B1 and Vitamin B3 caused oxidative stress and insulin resistance.

text: Cauchy problems with SPDEs on the whole space are localized to Cauchy problems
on a ball of radius R. This localization reduces various kinds of spatial approximation
schemes to finite dimensional problems. The error is shown to be exponentially
small. As an application, a numerical scheme is presented which combines the localization
and the space and time discretization, and thus is fully implementable.

text: Markov decision processes (MDPs) are standard models for probabilistic systems
with non-deterministic behaviours. Long-run average rewards provide a mathematically
elegant formalism for expressing long term performance. Value iteration (VI) is
one of the simplest and most efficient algorithmic approaches to MDPs with other
properties, such as reachability objectives. Unfortunately, a naive extension
of VI does not work for MDPs with long-run average rewards, as there is no known
stopping criterion. In this work our contributions are threefold. (1) We refute
a conjecture related to stopping criteria for MDPs with long-run average rewards.
(2) We present two practical algorithms for MDPs with long-run average rewards
based on VI. First, we show that a combination of applying VI locally for each
maximal end-component (MEC) and VI for reachability objectives can provide approximation
guarantees. Second, extending the above approach with a simulation-guided on-demand
variant of VI, we present an anytime algorithm that is able to deal with very
large models. (3) Finally, we present experimental results showing that our methods
significantly outperform the standard approaches on several benchmarks.
